hi Henrique,
Unfortunately its doesn't work, but like I said before, I can see the numbers for all Vlan or just for one vlan by using   show mac-learning domain vlan vlan id summary
what I need is a script/command that allows me to show the number by VLAN in one time (not total number in all vlans)
example : 
Vlan 1 = 420 
vlan 2 = 50
......
vlan n = 389
